I had to do something very similar just last night. The superblock on my
/usr partition got screwed up, and I couldn't recover it. The rest of the
system was fine. Of course, I had to deal with some other ugliness that
you're going to be spared (e.g. dpkg is in /usr; I had to find a
replacement!).
Try something like this:
# dpkg --get-selections > /root/packages
# cat /dev/null > /var/lib/dpkg/status
# dpkg --set-selections /root/packages
Then you should be able to run dselect, select [I]nstall from the menu,
and go, assuming your sources are up to date and pointing to the right
mirrors. Dpkg will ask you before overwriting any of your config files,
but just to be sure I kept a backup of /var and /etc. But that probably
won't be an issue for you, since you've got everything on CD.
You'll still have to go through /var and /etc and check those perms,
because most of the contents of those directories will not be
replaced. There may very well be a better solution to your problem. This
is what comes to mind first for me.
Good luck.
